3afb41655e avcodec/dca: Unavpriv dca_sample_rates
Said table is 64 bytes long and exported so that it can be used both
in libavcodec and libavformat. This commit stops doing so and instead
duplicates it for shared builds, because the overhead of exporting the
symbol is bigger than 64 bytes. It consists of the length of the name of
the symbol (2x24 bytes), two entries in .dynsym (2x24 bytes), two
entries for symbol version (2x2 bytes), one hash value in the exporting
library (4 bytes) in addition to one entry in the importing library's
.got and .rela.dyn (8 + 24 bytes).
(The above numbers are for a Linux/GNU/Elf system; the numbers for other
platforms may be different.)

012620aa1b avcodec/dca: avoid using bitstream reader in a non-standard way
Use proper get_bits.h functions instead of directly accessing index.

Avoid using bitstream reader in a non-standard way by directly accessing
index. Use bit shifting/masking operations instead.

db44b59980 avcodec/dca: clear X96 channels if nothing was decoded
The first X96 channel set can have more channels than core, causing X96
decoding to be skipped. Clear the number of decoded X96 channels to zero
in this rudimentary case.
